Mount Mayon has been spewing lava and flaming rocks, some as big as cars for the last month. Now scientist have warned that Wednesday full moon could spark off a major eruption.
The moons gravitational pull, the force behind the oceans high and low tides appears to be having a direct affect on the lava trapped within mount Mayon, and is being linked to all volcanic activity world wide.
Prievious full moons have been linked to at least three previous eruptions on mount Mayon, including the two most recent, one in 2000 and the other in 2001.
At least 30,000 people have been moved or evacuated from an 8km danger area around the volcano, but there are still many locals who refuse to leave their farms and livestock.
